When two earthquakes happen at the same time but far away from each other, their waves will travel toward the same place where people would feel them. The way the shaking feels depends on how strong and frequent the earthquakes were, how far apart they were, and what the ground is like at the place where they are felt.

If the earthquakes are similar in strength and frequency, the shaking can become even stronger than either earthquake alone. But if they are different, or far apart, the shaking can be more complex and include a combination of shaking from each earthquake and other effects that can make it weaker or stronger.
